DCE-MRI has been extensively used in monitoring
treatment response on many anatomies. However, this
technique was not fully explored in lung cancer due to
breathing motion. By using a mutual information
non-rigid registration method to eliminate body motion
and using modified Tofts Model and de-convolution
method, clinical relevant parameters could be extracted
from a breath-hold DCE-MRI to monitor treatment response
on NSCLC patients.
